Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Those panels are supplying the grid anyway and with angles like this in their lifespan they are going to generate mega watt hours less then their correctly installed counterparts. In a perfect world (with wider solar adoption) this would be considered a waste of panels.

Perfect being the enemy of good

Panels are cheap, and the single-phase inverters they are using are too.

Even with the odd placement, they are going to yield a few hundred watts per panel on sunny days. Since it’s so low most of it will be going directly to household consumption.

This doesn’t move the needle much globally speaking, but it’s also a tiny investment and (especially in Germany when even in sunny days the carbon footprint of what comes out of the grid is horrendous) it significantly lowers household carbon emissions.

Thats why I added the part about perfect world.

In it his house would be supplied from those panels anyway but much better placed.

And panels and inverters are cheap, but so is gasoline. Multiply it a bunch of times and the resources wasted get us another catastrophe.

Orientation doesn’t matter as much as you’d think on overcast days. And this is Germany. Also, transmission is a thing. So unless your “perfect world” also includes perfect weather and upgraded physics, you are just not really making sense.

In the end you’re just yet another person ginning up excuses for inaction by distorting facts. And god knows we good plenty of those.
